Finaly 5AFE Swapped in EE90

[Vaqas1]

I need to know if the below image is close to what the 5AFE ecu pinouts will be like? SER and Xulfiqar?

Guys i am facing rough idle problem. Some time it goes away and car RPM is fine at 900 other time it goes to 500 or 600 and stays there. In a day i face this issue 2 or 3 times when i face rought idle or fine idle.

What can be the problem?

Throtle body service?
Any sensor responsible for this?

Ser GTR you said set timing in diagnosis mode can you explain how can we get into that?

[Vaqas1]

the map sensor you are using is wrong - use a blue sticker square shape sensor, these yellow ones are usually found in diesels and cannot measure vacuum - the one you want should have "sensor assy vacuum written on it"

y.

Is this the one you are talking about? Taken from another thread

why It Looks So fimilar To me.....Ohh
Damn....You Are Showing Us a BT Pinout....How Funny

[SER_GTR]

Yea The Map sensor Shown Is Above Pics If From 5AFE 4AFE...
2ndly ISCV is responsible for idling .....i told u earlier....!!
the best thing to find a map sensor is to get it from part no....!!
leme find one for you...!!
about timing so yea...diagnosis mode......!!
Short TE1 and E1 on ECU like you do for retriving code.....then start it.........car is in diagnosis mode....adjust timing now......and after doing it...shutt of engine and remove jumper...

[Vaqas1]

Oh is it hehe. I just searched on Google. Cant find a proper 5AFE Pinout.

It will be difficuilt to carry out any experiment without one

[Vaqas1]

ISCV we checked it was ok. how to fix if its ISCV service or replacement?

ISCV can get jammed so u have to make sure mechanism is not jamming inside.....remove it and you have to physically check it by moving it....!!

[SER_GTR]

If Map sensor is different means the engine you got is not having its genuine map sensor.....!!
match the map sensor with part no i mentioned above

[Vaqas1]

Okay. I will get that Done. and also the correct map sensor.

Ser you helping a lot. Thx for sharing your knowledge and experiance

change your MAP sensor first - your idling issue will resolve itself if everything is OK - running this sensor currently will make the ECU act funny at different rpms

[Xulfiqar]

about the pinouts - open up the ECU - the pinouts are printed on the circuit board. They are very simple to dechipher..

Anyways if you completely understand the pinouts - you already have a diagram on this thread - open up the ECU - make your own connector diagram and see what the pin codes connect to in the diagram; simple as that

[SER_GTR]

some ECU's also don't have it printed Xulfiqar !
but those 5afe 4afe one's might have on it.....!!
my BT ECU don't have it but i have pinout so no issues..

[Xulfiqar]

all the 4afe and 5afe whether orange or black sticker would have them - the 4AGE 20V ones dont - same with the advanced JZs

[Vaqas1]

Ok thanks a lot Xulfiqar

BTW any thing i can do to save my ECU from blowing up or stop working from my testing

[SER_GTR]

^^ Open Your Mind
Buy A DMM And Check Connection 7 Times And Make Sure Its Same Before Trying
Also if You Share your ECU Pics......we can also give you idea about pinouts for verification....!!
it won't blow unless o until you short some wires or put out some very wrong connections......!!
have 15A ECU fuse 1st in +b and BATT connections....

AGAIN SORRY FOR HIJACKING THE THREAD

1) so i have checked my own engine's map sensor....

is it the right one? googled its no. and i think its from a 1JZ-GE! My engine doesnt have any idling problems though. (mashallah)

2) My AC was wired up by cutting through the stock harness of the previous 2E. here you can see the connector that goes onto the AC compressor and the extra wires spliced open. By looking at the wires, can i say i have an AC amplifier? the new compressor accepts only 3 wires as seen on connector with only three pins in it. Which wire to go where?

3) I was getting error code 42 whenever i drove above 3000rpm in 3rd gear with light throttle or cruising arnd 2000-2500rpm onwards in 5th gear. its an error that gets erased once ign is switched off....reappears if i recreate the same driving conditions. Its an air temp sensor error from what i know. how to solve??

These are some of the correct MAP sensors that you can use

firstly these things should be written on it

SENSOR ASSY, VACUUM
TOYOTA
89420-20110(actual part number)
100798-1830
(nippondenso logo) DENSO. JAPAN

Other part numbers which also work are

89420-12060
89420-12070
89420-22200

Thank you.
